OK, thinking of trying water cooling again, with an mATX board. And I've narrowed my choices to either a Fractal Mini or a Silverstone TJ08B-E. The former will use a 240mm radiator and the later will take a 180mm. I'm going to be cooling a 2500k and maybe a 6870 (might bump it up to a 6950). For these components, will one (in general) cool better than another? I know it depends some on brand, so I'm speaking in generalities. For the price, I'm likely to do a thin XSPC for the Fractal and a Magicool 180 for the Silverstone. Thanks for any help, ideas, or experience.
